World Population Calculator

This calculator requires the use of Javascript enabled and capable browsers. This is designed with an algorithm combination of calculation and estimation to approximate the world population at any given time. Based on the current displayed time and date, you can hit the refresh button of your browser and see the world population estimate change by the second, or the program will do it for you about every 15 to 20 seconds. The US Bureau of the Census may have a different World Population projection. You can also see the US Population there.
